Procedure

29.5 g of the catalyst is charged with a 5/1 moles methanol/mole phenol mixture with LHSV of 0.68 h-1. The gaseous mixture, diluted with N2 as the carrier gas after its vaporization at 140° C., is converted to an extent of 83% at 372° C. The yield is 34% of 2,6-dimethylphenol and 47% of o-cresol. After an operating period of 40 hours, the catalyst activity and selectivity decrease sharply.
